- Product

- Device & OS
- Mac
- Scenario
- Attempting to install the latest software updates for Microsoft Office applications on a Mac.
- Observed behavior
- An error message appears stating that 'One or more update packages could not be downloaded,' causing the update process to fail.

Manually Install the Latest Microsoft AutoUpdate Tool
Downloading and installing the newest version of Microsoft AutoUpdate directly from Microsoft resolves broken update package downloads.
Microsoft Office relies on a background application called Microsoft AutoUpdate (MAU) to fetch and install patches. If MAU itself becomes too outdated, it loses the ability to securely connect to Microsoft's servers, resulting in the 'packages could not be downloaded' error.
Visit the official Microsoft Mac download page and download the latest Microsoft AutoUpdate package (.pkg) to your computer.
Open your Mac's Downloads folder, locate the downloaded AutoUpdate .pkg file, and double-click it to launch the installation wizard.
Follow the on-screen prompts to complete the installation of the new AutoUpdate tool.
Open any Microsoft Office application (like Word or Excel), click on 'Help' in the top menu bar, and select 'Check for Updates' to run the updater.
Once the pending Office updates are successfully downloaded and installed, restart your Mac to ensure all background services are running correctly.

Frequently Asked Questions
Why does the Microsoft AutoUpdate installer fail to launch automatically?
macOS security settings (Gatekeeper) or web browser configurations can sometimes prevent downloaded packages from launching automatically. You can bypass this by navigating to your Downloads folder and manually double-clicking the .pkg file.
Can I update Microsoft Office for Mac without using AutoUpdate?
While AutoUpdate is the standard method, you can also download standalone update installers directly from the official Microsoft Office release history webpage for Mac.
Will updating the AutoUpdate tool delete my existing Office documents?
No, updating the Microsoft AutoUpdate tool only refreshes the background update utility itself. It will not affect your personal documents, saved preferences, or Office application settings.
